However, the most important aspect of calf force production is actually linked to the elastic properties of the calf and achilles tendon complex.<\/p>\n<p>When the calf muscle contracts eccentrically, the achilles tendon is loaded like a spring with potential energy, and then recoils to generate a powerful force.

However, the calves consist of two distinct muscles: the meatier superficial gastrocnemius (which has a medial and lateral head), and the underlying flatter soleus muscle which fans out to the sides.<\/p>\n<p>If you trace your thumb from your shinbone (tibia) inwards (medially) to the point where you drop off from the bone to softer muscle, that\u2019s the soleus.<\/p>\n<p>The soleus consists of predominantly (typically around 80%) type-1 muscle fiber types which are \u201cslow-twitch, endurance\u201d fibers. For reference, the gastrocs are typically closer to 50\/50 ratio of type-1 and type-2 (\u201cfast twitch, power\u201d fibers).
